One option would be to run an NFS server in domain 0 and boot all
of the other domains using root-on-NFS from directories on domain
0's filesystem. The README.CD talks about how to have them
sharing a single /usr (and /lib and /sbin) if you want to save
space.

ram disks work precisely the same way they do under normal
Linux. Follow the instructions in REAME.CD for building your own
CD, then inspect irtree/linuxrc. It populates the root file
system from root.tar.gz. I'm not sure that ramdisks are what you
want, though...
